Already, a thousand blogs and columns insist the Intergovernmental Panel on Climate Change’s new report is a rabid concoction of scare stories whose purpose is to destroy the global economy. But it is, in reality, highly conservative. Reaching agreement among hundreds of authors and reviewers ensures that only the statements which are hardest to dispute are allowed to pass. Even when the scientists have agreed, the report must be tempered in another forge, as politicians question anything they find disagreeable: the new report received 1,855 comments from 32 governments, and the arguments raged through the night before launch. In other words, it’s perhaps the biggest and most rigorous process of peer review conducted in any scientific field, at any point in human history.
